Vesta - netshe elisemkhathini ebonakalayo ngokubona okubonakala ngeso lenyama

Vesta - netshe elisemkhathini, ngezindlela eziningi ezithakazelisayo. Kuyinto kuphela into enjalo ukuthi kungabonwa ngeso lenyama. Uma kuqhathaniswa isisindo, kanye nosayizi Vesta aphakeme kwamanye asteroyidi kakhulu aziwayo esikhaleni phakathi umzila wenyanga Jupiter ne-Mars. Ngu nemingcele yayo kuba ngisondelene nakakhulu iplanethi yemifino. Akhiwe ibhande main elisemkhathini, Vesta libhekisela emizimbeni kwakhiwa emhlabeni isikhathi esifanayo ngokuthi uMhlaba, futhi ngenxa yalokho, kungaba ukutshela okuningi esidlule kwesimiso sethu.

ukutholakala

Vesta - netshe elisemkhathini, ezatholakala ngo-inqubo efuna iplanethi phakathi Mars kanye Jupiter. Ngokwe-theory, ukusatshalaliswa ezungeza emkhathini uzungeza ilanga kungaphansi kwemithetho ethile. Zonke ezaziwayo ekuqaleni kwekhulu XIX izwe angena kanjani kulo mbuso theory. Okuwukuphela Jupiter ne-Mars. Isikhala omkhulu phakathi kwabo kwaba ukufihla i iplanethi engaziwa. Phakathi search wakhe amaningi izakhi Main Kwatholakala ibhande elisemkhathini.

Vesta zatholakala e 1807 by Heinrich Wilhelm Olbers. Omunye usosayensi, uCarl Gauss, wamnika igama unkulunkulukazi wamaRoma le. Igama wanamathela futhi zisasetshenziswa nanamuhla.

amapharamitha

Ngemva Ceres chasiselwe amaplanethi yemifino, Vesta ngobukhulu endaweni yesibili phakathi asteroyidi ngemva uPallas. Amapharamitha Ezazimzungezile - 578 × 560 × 458 km. asymmetry lubonakale bunjwa, kanjalo uvimbele ukudala ezinye kuyosishintsha iplanethi yemifino. Uma kuqhathaniswa isisindo (2.59 × 10 ²⁰ kg) kuba phambili palladium, okungukuthi, e-main elisemkhathini ibhande oludlula kule ipharamitha, kodwa zonke Ceres efanayo.

Ingabe le nguzunga Vesta emkhathini?

Asteroids kungukuthi nje wehluke ekilasini mayelana nezinto zasemkhathini. Kusukela amaplanethi bayehluka ezintweni eziningi nemingcele: isayizi, simo, isisindo nokunye. Izimpawu netshe elisemkhathini, akamvumelanga ukuba ubambe imvilophi igesi. Ngakho impendulo yombuzo othi "Ingabe le nguzunga Vesta, umkhathi" - ezingezinhle. Kakhulu igobolondo tenuous igesi ekhona ku Ceres. emizimbeni Okunye ezonini main abakwazi ukuqhosha isici ezifana le nguzunga Vesta. It has isimo Earth, Venus, Mars, igesi imidondoshiya abanye babangane bakho. Asteroids ngoba sincane kakhulu.

Kanjani ukubona Vesta elisemkhathini?

Vesta ngenxa yenkazimulo kungabonwa ngeso lenyama. Nakuba-ke zingaphansi ngobukhulu Ceres futhi uPallas, kodwa elinesimo reflectivity ezinkulu. Okunye asteroyidi nge Umhlaba ingabonakali ngaphandle nemishini ekhethekile.

Isikhathi esingcono kakhulu ukucinga asteroyidi esibhakabhakeni - izinsuku ukuphikiswa, lapho efika ibanga okungenani ukuba Earth. Kulezi nezikhathi, isicwebezelisi yayo luyanda 5,1 m (inani eliphansi lokhu ipharamitha - 8,5 m). Isikhathi sokugcina nesimo esinjalo senzeka ngo-Ephreli 2014.

Vesta iseduze ibanga okungenani ukuba iplanethi yethu kanye njalo eminyakeni 3-4. Ngaphandle isibonakude ukuze sibone kungenzeka kuphela nemibandela ukubonakala okuhle. Kulokhu, it akahlukile izinkanyezi abavamile.

ezinyakazayo

Emzileni Vesta itholakala engxenyeni engaphakathi main elisemkhathini ibhande. ezakheke kuphela kancane enwetshiwe - cishe umbuthano ephelele. I-orbit elinesimo enyakazayo kancane indiza Ecliptic. Vesta kwenza omunye revolution emhlabeni Sun eminyakeni 3.6. Ngesikhathi esifanayo ngesikhathi ukunyakaza kwabo emzileni iplanethi akusho ukuwela elisemkhathini.

Isikhala probe Dawn

Ngo-2011, ngo-July, Vesta lidlule iphuzu ibanga okungenani kusukela kule planethi yethu. Le nkathi isetjentiswe isifundo eningiliziwe elisemkhathini. Emuva ngo-2007, ngaya Vesta, Dawn AMC. Inhloso ye-unit - ekutadisheni elisemkhathini, kanye iplanethi yemifino Ceres.

A orbit isiyingi Vesta Dawn weza Julayi 16, 2011. Ngu-December 12, ifinyelele engamamitha ubuncane phezu elisemkhathini. Phakathi imisebenzi unit babe nesilinganiso emkhakheni okudonsa, ekutholweni nomkhakha we neutron nama-gamma ray kokuvela ekwindla ray cosmic ku le nguzunga Vesta. Izithombe into beza Umhlaba ngo-December 13.

Dawn AMC kwesokunxele le nguzunga 5 Septhemba 2012 waya Ceres. Kuze kube manje (Disemba 2015), umshini siyaqhubeka ukusebenza emzileni iplanethi yemifino.

showplace

Vesta - netshe elisemkhathini ngokucophelela "zihlolwe" isibonakude "Hubble". Lezi zifundo yayiqhutshelwa 90-yalolucwaningo kwekhulu elidlule. "I-Hubble" efunde kobuso elisemkhathini. Ingxenye umxhwele kakhulu impumuzo Kwatholakala emgodini omkhulu, kamuva esabizwa ngokuthi rheasilvia. Ngokulandelayo, mhlawumbe osale ushayisile, elinesimo ububanzi 460 km kanye 13 km ukujula. Ososayensi namanje Awukwazi ukuphendula umbuzo kanjani Vesta wakwazi ukusinda buhlungu ezinjalo.

Dawn AMC naye wafundelwa isimo wentaba. Ngokwe ezizathwini of ososayensi rheasilvia owabunjwa eminyakeni eyodwa billion edlule. Pool wentaba kancane efihla nokuncane umphumela lasendulo, emgodini okuthiwa Veneneyya. Maphakathi rheasilvia kuba amagquma 22 km okusezingeni eliphezulu 180 km ububanzi. Ngu nemingcele yayo kuba phambili we Olympus giant on Mars, ngaphambili kubhekwe entabeni eyaziwa eliphakeme esimisweni sonozungezilanga.

Ososayensi bathi ukuthi into ukhiphe ngu ukushaqeka, wakhonza njengephayona indaba for nesenzakalo lezinto nomndeni ekilasini Vesta asteroyidi V

Abacwaningi ubhekisa ukunakekela kwakhe ukuze izinto ezifana bakwazi ukutshela okuningi mayelana nesikhathi lapho isimiso sonozungezilanga yayakha. Vesta - netshe elisemkhathini, ukubunjwa yayo eduze amaplanethi Earth-like. Ezimweni eziningi, lokhu uzokutshela izazi zezinkanyezi zikwazi ukufunda abaningi esidlule ngisho nocezu kwethu Galaxy.
